I had the same exhaust as you last year, and it was loud as f%ck.
Magnaflow cat, 22" resonator, and dual tip muffler.
The 2.5" piping keeps it loud, and those components aren’t that quiet.
You can get Magnaflow components smaller than 2.5", I’m pretty sure I’ve seen 2" or 2.25" around.
Mine was on my Maxima, but still, same specs, and it was uber loud.
